Hetai Custom Bolts specializes in high-precision, custom-engineered bolt manufacturing tailored for demanding industrial applications. With state-of-the-art cold-forging and CNC machining capabilities, Hetai delivers tailored fastening solutions that meet exact client specifications across diverse sectors, including automotive, heavy machinery, aerospace, and structural engineering.
Custom Bolts
Engineered to exact dimensional and performance specifications, offering total flexibility in thread design, head configurations, and drive types.
Non-Standard Bolts
Tailored solutions built outside standard ISO/DIN/ANSI specifications. Ideal for specialized machinery, legacy equipment replacement, or unique engineering constraints that off-the-shelf fasteners cannot fulfill.
Special-Shaped Bolts
Custom-molded and complex-geometry fasteners—including T-bolts, eye bolts, square-head bolts, hook bolts, multi-stage stepped bolts, and asymmetric designs—built to solve intricate structural and mechanical mounting challenges.
Core Capabilities & Value Proposition
Customization Range: Full freedom in selecting thread pitch, head style (hex, flange, socket cap, custom), shank length, and drive types.
Material Versatility: Processing high-grade carbon steel, alloy steel, stainless steel (304, 316), brass, and specialized titanium alloys.
Surface Finishing: Advanced corrosion-resistant coatings including zinc-plating, hot-dip galvanizing, Dacromet, black oxide, and custom anodizing.
Property Classes: Standard and high-tensile grades (e.g., 8.8, 10.9, 12.9, Grade 5, Grade 8) designed for extreme mechanical stress.
Quality Assurance: ISO-certified production adhering strictly to international standards (DIN, ISO, ANSI/ASME, JIS) with comprehensive non-destructive testing and material certification.
Hetai Key Service Advantages
Tailored Engineering Support: Complete Design for Manufacturability (DFM) reviews to optimize custom fastener strength, cost, and weight.
Flexible Volume Capabilities: Efficient production workflows for low-volume prototyping, bridge production, or large-scale manufacturing.
Rigorous Quality Assurance: 100% optical sorting, thread gauge inspection, tensile strength testing, and full material certification (MTRs).
Industry Applications
Aerospace & Defense: Lightweight titanium special-shaped bolts and high-strength structural studs.
Automotive & EV: Custom battery-pack fasteners, high-torque chassis bolts, and specialized terminal pins.
Heavy Machinery & Energy: Large-diameter non-standard anchor bolts, flange studs, and corrosion-resistant marine fasteners.
Medical Devices & Electronics: Micro-sized non-standard screws, captive fasteners, and non-magnetic stainless components.
Whether you require small-batch prototyping or large-scale OEM production runs, Hetai Custom Bolts offer the mechanical strength, exact tolerances, and long-term durability your structural and mechanical projects demand.
